Each intersection has a traffic signal and the speed limit it 50km/h. Suppose you are driving from west at speed limit. When you are 10m from the first intersection all lights turn green. The lights are green for 13 seconds each. (a) calculate time needed to reach third stop light. Can you make it through all three lights without stopping? (b) Another car was stopped at first light when all the lights turned green. It can accelerate at the rate of 2.0m/s^2 to the speed limit. Can the second car make it through all three lights without stopping? From first light to the second light the distance is 55m. from the second light to third light distance is 85m.
Any help is greatly appreciated!
